Created date in node author details summary not displayed in current locale

klaasvw → changed the visibility of the branch 3482699-created-date-in to hidden.

The MR addresses the issue by applying Date.toLocaleDateString to the date string.

Appears to have pipeline errors.

Issue summary appears to be missing some sections, particularly clear steps for reproducing the issue. May require test coverage.

Tests all passed with the format change which tells me we lack any test coverage for the output. Went looking and confirmed, we have CollapsedSummariesTest but that's testing view port specific things. SettingSummariesContentTypeTest is testing it on the Node type itself. I've added NodeDetailsSummariesTest which covers the author and promoted option summaries

Think breaking up to it's own test file should be fine. Looking in node javascript test folder some already seem to be very specific. Change LGTM.
